tstokenlib 1.3.0

An implementation of the TSL1 Token Protocol for the BSV blockchain.

1.3.0

On-chain Identity Anchoring & Hand-optimized Scripts

• Mandatory Rabin identity anchoring for NFT issuance: PP1 now verifies a Rabin signature (s² mod n == sha256(identityTxId || ed25519PubKey) + padding) during issuance, enforcing that only the holder of the identity key can mint tokens. The rabinPubKeyHash is a new required parameter on createTokenIssuanceTxn and PP1LockBuilder.
• Hand-optimized PP1 script: Replaced the ~11KB compiled sCrypt template with a 2.5KB hand-optimized Bitcoin Script (~4.5x reduction).
• Hand-optimized PP5 script: Replaced the ~56KB compiled sCrypt template with an 8.2KB hand-optimized Bitcoin Script (~6.7x reduction).
• Rabin cryptographic utilities: New Rabin class with key generation, signing, and verification (lib/src/crypto/rabin.dart).
• Fungible token support: FungibleTokenTool with full lifecycle — mint, transfer, split, merge, and burn operations.
• Issuer identity anchoring: IdentityAnchorBuilder and IdentityVerification for linking tokens to ED25519-signed issuer identities.
• Configurable fees: TokenTool and FungibleTokenTool accept defaultFee and networkType constructor parameters.
